Nitric oxide: a new role in intensive care
1Ulster Hospital, Dundonald, Belfast, Northern Ireland.
Summary
Inhaled nitric oxide (NO) improves oxygenation and reduces pulmonary vascular resistance. Recent research highlights NO
Area of Science:
- Biomedical Science
- Physiology
- Pharmacology
Background:
- Inhaled nitric oxide (NO) has a 30-year history of clinical use for improving oxygenation and reducing pulmonary vascular resistance.
- Over the last 15 years, scientific understanding has deepened regarding endogenous NO's roles in cellular processes, including cell surface receptors, mitochondria, and intracellular calcium and superoxide radical signaling.
Purpose of the Study:
- To explore the potential therapeutic applications of administered NO or NO donors.
- To investigate NO's role in conditions like systemic inflammatory response syndrome (SIRS) and ischemia-reperfusion (I/R) injury.
- To assess NO's utility in patients undergoing procedures involving blood exposure to artificial surfaces.
Main Methods:
- Review of existing literature and clinical data.
- Analysis of animal and human experimental studies.
- Investigation of NO's intracellular and mitochondrial mechanisms.
Main Results:
- Evidence suggests a potential therapeutic role for NO administration in specific clinical contexts.
- NO influences critical cellular pathways relevant to inflammatory and ischemic conditions.
Conclusions:
- Administered nitric oxide and its donors show promise for treating systemic inflammatory response syndrome and ischemia-reperfusion injury.
- Further research is warranted to fully elucidate NO's therapeutic potential in critical care settings, including extracorporeal circuits.

01:28Nitric Oxide Signaling Pathway
6.0K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
